Reword the rationale
Reword the Abstract to be more clear
Refine the Explicit bootstrap section
Simply the Pre-installation section

This now needs justification for ``make install`` and
``make altinstall`` not bootstrapping pip.
Refine the virtual environment section
Refine the recommendations for dowstrean/other distributors
Remove the section for "Why a private pip" as it has already been addressed.
Refine the Policies and Governence section
Rework the counter points into an Appendix
Link the first mention of pip
